Modelling spatial and temporal dynamics of rhizosphere exudation. Existing crop root systems are poorly suited to Australian soils with low nutrient availability. Using a simulation model to develop computer-aided design of 3-D root structure and function, tailored to particular environments, this project will enhance breeding for increased nutrient-use efficiency.
Optimising crop root systems to enhance capture of soil water and nutrients. The project’s goal is to improve crop breeding for increased efficiency of acquiring soil resources. Increasing a crop’s efficiency in capturing soil resources (water and nutrients) is an imperative task in ensuring food security. This project plans to use barley as the model cereal crop and characterise root traits in a panel of cultivars assembled to represent maximum diversity as well as in biparental mapping populat ....Optimising crop root systems to enhance capture of soil water and nutrients. The project’s goal is to improve crop breeding for increased efficiency of acquiring soil resources. Increasing a crop’s efficiency in capturing soil resources (water and nutrients) is an imperative task in ensuring food security. This project plans to use barley as the model cereal crop and characterise root traits in a panel of cultivars assembled to represent maximum diversity as well as in biparental mapping population followed by association and linkage mapping to identify genetic markers linked with specific root traits. These markers will be incorporated into a computer model of 3-D root structure and function. The enhanced computer model would be able to simulate optimal root systems for specific environments and generate a list of selectable root-trait markers.Read moreRead less
Tailoring physiologically-based nanomaterial fertilisers for the biofortification of zinc in broadacre crops. Soil zinc deficiency is a global issue causing low crop yield and malnutrition. This project will develop a new class of fertiliser formulations by combining advanced chemistry techniques with plant physiology knowledge and nanomaterial manufacturing. These products will be designed for enhanced agronomic efficiency and environmental safety.
Enhancing phosphorus use efficiency in macadamia for sustainable production. Macadamia nuts are an iconic native Australian product worth $287 million annually at the farm gate. Phosphorus fertiliser management currently threatens price premiums for sustainable production in high value European Union export markets, and ‘social license’ to farm in their densely populated coastal production areas. The project aims to exploit adaptive root and shoot traits for phosphorus efficiency found in Austra ....Enhancing phosphorus use efficiency in macadamia for sustainable production. Macadamia nuts are an iconic native Australian product worth $287 million annually at the farm gate. Phosphorus fertiliser management currently threatens price premiums for sustainable production in high value European Union export markets, and ‘social license’ to farm in their densely populated coastal production areas. The project aims to exploit adaptive root and shoot traits for phosphorus efficiency found in Australian native plants to optimise phosphorus fertiliser management and set the platform for breeding macadamia root stocks/varieties that require less phosphorus fertiliser. The outcome will be a macadamia industry that is able to maintain current market price premiums and maintain social license to farm in coastal Australia.Read moreRead less
Transition from phosphate mining to an economically, environmentally and socially viable agricultural industry on Christmas Island. The main industry on Christmas Island is mining of rock phosphate, but supplies will run out between 2025 and 2030. Consequently, there is an urgent and compelling need to develop other economic industries to support the resident island population by the time mining ceases. This project aims to utilise the project team’s extensive knowledge on legumes, nitrogen fixi ....Transition from phosphate mining to an economically, environmentally and socially viable agricultural industry on Christmas Island. The main industry on Christmas Island is mining of rock phosphate, but supplies will run out between 2025 and 2030. Consequently, there is an urgent and compelling need to develop other economic industries to support the resident island population by the time mining ceases. This project aims to utilise the project team’s extensive knowledge on legumes, nitrogen fixing bacteria and plant growth promoting bacteria to establish the basis for a viable agricultural industry on the Island. The project aims to provide: reliable and sustainable food sources for the local population; potential food export opportunities to southeast Asia; environmental benefits from the improvement of soils; and economic development of allied agricultural industries.Read moreRead less

This research hub aims to provide Australian growers and industrial stakeholders with improved plant materials to maximise production, environmental sustainability and profitability. In particular, the research aims to improve the nitrogen delivery capacity of legumes and their resilience to abiotic stress, which will be an important consideration as our climate changes. Grain legumes are often grown in rotation with cereal crops for their high nutritional seed value and their unique ability to develop a self-sufficient nitrogen-fixing symbiosis with soil bacteria. Maintaining legume productivity against the challenges of climate change and the need for increased food production is important to the future of Australian agriculture.Read moreRead less
Crop genome complexity: sulphur metabolism and mustard pungency. This project aims to explain the molecular basis of crop plant plasticity in the context of a complex crop genome. It will determine how epigenetic mechanisms contribute to regulating the yield of a secondary metabolite harvested from mustard plants in response to variation in environmental factors. Specifically it will explore the relationship between sulphur metabolism and small RNA regulation of glucosinolates. The project shoul ....Crop genome complexity: sulphur metabolism and mustard pungency. This project aims to explain the molecular basis of crop plant plasticity in the context of a complex crop genome. It will determine how epigenetic mechanisms contribute to regulating the yield of a secondary metabolite harvested from mustard plants in response to variation in environmental factors. Specifically it will explore the relationship between sulphur metabolism and small RNA regulation of glucosinolates. The project should uncover the role that duplicated genetic loci and epigenetic marks play in regulating tissue-specific gene networks, particularly in field-grown environments. The project will explore how duplication of genes enables a crop such as mustard to respond to application of sulphur fertiliser and regulate the stockpiling of the 'hot' volatile oil in mustard seed, a valuable export commodity.Read moreRead less

The objective of this project is to use emerging genomics technologies to identify and characterize soil bacteria that allow the replacement of current agricultural fertilisers, which have significant environmental and economic disadvantages, with sustainable biological fertilisers. Soil bacteria can greatly enhance phosphate solubilization and hence availability for plant growth. Beneficial microbes will be identified from our existing soil collection and their performance and persistence optimised. Concurrently, our industry partners will develop suitable microbial formulations for application. The outcomes of the project will be the use of biological fertilisers to enhance crop productivity in an environmentally sustainable manner.Read moreRead less

This project seeks to evaluate the unique properties of graphene to more effectively engineer novel fertilizers with properties that can enhance nutrient efficiency and reduce losses to the environment. More efficient and effective fertilizer formulations are needed to improve nutrient use efficiency in agricultural systems globally, and for effective biofortification of staple food crops with essential micronutrients. Nitrogen may be lost from soil through leaching and gaseous losses to the atmosphere. Phosphorus, as well as copper, manganese and zinc, are prone to reactions in soils and during manufacturing which reduces their effectiveness.Read moreRead less
